CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 707,733, dated August 26, 1902.

Application filed June 18,1902. Serial No, 112,233- (No model.) 7

To all whom it ntay concern;

Be it known that 1, WILLIAM F. TALBERT, a citizen of the United States,residing at Funkstown, in the county of Washington and State of Maryland, have invented a new and useful Corn-Planter,of which the following is a specification.

This invention relates to corn-planters; and;

ment, and relative disposition of the compo nent parts of the device, which will be herein-.

after fully described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan View of a corn-planter constr'ucted in accordance with my invention. Fig. 2 is alongitudinal vertical sectional view of the same. Fig. 3 is a detail plan view of a portion of the front end of the lower frame of the machine, showing the front end of one of the plowbeams connected therewith.

Corresponding parts in the several figures are indicated by like characters of reference.

My improved corn-planter is provided with two separate frames, the upper frame 1 being supported upon the axle 2, which is mounted revolubly in boxes or journals 3 upon the under side of said frame. The traction-wheels 4 4 may be fixed upon the ends of the axle; but I prefer that one of them shall be mounted revolubly thereon for convenience in turning.

The upper frame 1 is composed of side pieces 5 5, upon the under sides of which the boxes 3 are suitablysec'urcd. The rear ends of said side pieces 5 5 are bent inwardly toward each other, as shown at 6, and are provided with overlapping ends 7, shouldered, at shown at b, so that when the side pieces are brought closely together the said overlapping ends shall abut against the shoulders of the opposite side pieces. Connectingbolts 9 are provided, and the overlapping ends are provided with series of perforations for the reception of said bolts to permit connection to be made at various points of adjustment. The side pieces 5 are provided on their inner sides near their front ends with brackets 11, extending inwardly toward each other and overlapping each other, and connecting-bolts are provided whereby the said overlapping'ends may be secured at various points of adjustment, each end being provided with a series of transverse perforations for the reception of said bolts.

The front ends of the side pieces 5 of the upper frame are bent or curved downwardly and inwardly, as shown at 14, and said depending ends are transversely perforated for the reception of a connecting-bar 15, which pivotally supports what may be termed the lower frameof the machine. Said. lower frame comprises, especially, the beams 16 of the plows or furrow-openers, the front ends of which are bifurcated, as shown at 17, and transversely perforated for the reception of the connecting-rod 15.

18 designates a yoke, the ends of which are transversely perforated also for the reception of the connecting-rod 15, the said perforated ends of the yoke engaging the bifurcated front ends of the beams 16, thus effecting a very secure and at the same time a sufficiently flexible connection of the parts. It will be seen that the ends of the yoke engaging the bifurcated ends of the plow-beams prevent the latter from spreading outward, while the downturned front ends of the side pieces of the upper frame bear against the inner' sides of the bifurcated ends of the plow-beams, thereby spacing them apart.

The yoke 18 is composed of two separate parts or members 18 18, overlapping each other and connected adj ustably by means of 5 of the yoke 18.

thus serve not only to support the tongue upon the frame, but also to assist in connecting the parts of the latter together. A coupling pin or bolt 22 extends vertically through the tongue and through the central portion This provides an additional connection between the upper and lower frames andserves likewise forzthe attachment of a centralbracket 23, corresponding with the ends of the yoke 18 and having a transverse perforation for the accommodation of the connecting rod 15. To this bracket, which has been illustrated in Fig. 3 of the drawings, the bifurcated front end of one of the plow-beams 16 maybe connected. This may sometimes be desired, as when it is desired to use three plows or if only a single centrally-disposed one is required.

The right-hand side of the upper frame supports a rack-segment 24, which forms one of the bearings for a transverse shaft 25, the

.opposite end of which is journaled in a box 28 at the opposite side of the frame.

- shaft 25 is composed of two separate members 25 and 25, the latter of which has a The socket 27, in which the squared end of the shaft member 25 is slidinglymounted. It will thus be seen that these shaft members revolve in unison, thus practically constitutin'g'a single shaft, while the sliding connection between them enables the sides of the frame to be adjusted laterally with relation to each other without interferingwith the operation of this part of the device.

The ends of the shaft members are provided with cranks 30, having pivotal connection 8 with the upper ends ofpitmen 31, the lower bear against the brackets 32, thereby tending to force the plow-beams in a downward direction. These springs permit the plowbeams to have anupwardly-yielding move- .ment, permitting them to ride over obstructions whichmight otherwise tend to injure parts of the machine.

The shaft member 25 carries a lever 34,

' having a dog 35, operated by a handle 36 and engaging the teeth of the rack 24 and operating to maintain the lever and shaft at any desired adjustment. By this means the shaft may be tilted in its bearings, thus throwing the cranks to elevate or depress the plowbeams and the parts supported thereon, as may be desired. The plow-beams 14 support near their front ends boxes or bearings 37, in which a transverse shaft. 38 is revolubly mounted. Neartheir rear ends the said plowbeams support the seedboxes or hoppers 39, the sides of which afford bearings for a shaft 40. The rear ends of the plow-beams also carry the standards 41, supporting the furrow-openers 42 and covering devices 43. All

these parts, as well as the seeding mechanism, may be of any suitable approved construction, and as regards the seeding mechanism, which is no part of the present invention, no attempt has been made to illustrate it in the accompanying drawings.

The axle of the machine is provided with a clutch consisting of a fixed member 44 and a sliding member 45, which latter may be operated by a lever -46, disposed in a position convenientto the driver, to'throw it into,or out of engagement with the fixed clutch member 44. Normally, it is held in such engagement by the action of a spring 47, coiled upon the axle between the outer end of said sliding clutch member and a collar 48, fixed thereon. A notched beveled-edged projection 49 extends laterally from the tongue, as shown'in Fig. 1. W'it-h it the lever 46 may be placed in engagement when it shall be desired to retain the sliding clutch member 45 out of engagement with the fixed clutch member 44 against the tension of the spring 47.

The sliding clutch member 45 carries a series of differently-sized sprocket-wheels 49, any one of which may be connected by a chain 50 with a sprocket-wheel 51 upon the shaft 38. The sprocket-wheel 51 has a hub 52, provided with a set-screw 53, whereby it may be secured in any desired position upon the shaft, thereby enabling it to be placed in V .which has its bearings in the seedboxes and which serves to actuate the seed-dropping mechanismof the machine. The shaft 40 is composed of three separate joints or members 40 40 40", the central one, 40, being connected with the end sections 'by means of sleeves 57, which permit the said three sections to revolve independently. By this means when it shall be desired to use only one side of the planter one of the chains 55 may be removed, and thus motion will be transmitted only to the planting mechanism at one side of the machine. It is obvious that the sprocket-wheels 56 are to be mounted upon the end sections 40 of the shaft 40. I desire to state with relation to this that, while it is preferred that the chains 55 and the sprockets for transmitting motion to the shaft 40 should be arranged between the hoppers of the machine, this is unimportant, as they may be equally well arranged adjacent to the outer sides of said hoppers, as shown in dotted lines in Fig. 1.

As will be readily understood, the axle of the machine, as well as the shafts 15, 38, and 40, should be made of sufficient length to en- ICC able the sides of the frame to be separated to the widest point of adjustment without interfering with the usefulness of said shafts. They have been so shown in the drawings. In like manner the construction of the shaft 25 of two sections having sliding engagement with each other provides for the extension of said shaft to any length that may be required at any point of adjustment of the side members of the frame of the machine.

A spring 60 is preferably coiled upon the bolt 22 between the tongue 19 and the yoke 18 or the bracket 23, extending rearwardly from the latter, for the purpose of spacing the said yoke and tongue apart.

An ordinary spring-seat 61 is mounted in the usual manner upon the tongue of the machine in a position which will enable the driver to have convenient control of the levers 3a and 4:6.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States 1.
